Heien v. North Carolina<\/a>, 2014 U.S. LEXIS 8306 (Dec. 15, 2014): Mistake of law can justify a stop on reasonable suspicion. [So ironic for Bill of Rights Day.] The Syllabus:
\n<\/p>\n

Following a suspicious vehicle, Sergeant Matt Darisse noticed that only one of the vehicle\u2019s brake lights was working and pulled the driver over. While issuing a warning ticket for the broken brake light, Darisse became suspicious of the actions of the two occupants and their answers to his questions. Petitioner Nicholas Brady Heien, the car\u2019s owner, gave Darisse consent to search the vehicle. Darisse found cocaine, and Heien was arrested and charged with attempted trafficking. The trial court denied Heien\u2019s motion to suppress the seized evidence on Fourth Amendment grounds, concluding that the vehicle\u2019s faulty brake light gave Darisse reasonable suspicion to initiate the stop. The North Carolina Court of Appeals reversed, holding that the relevant code provision, which requires that a car be \u201cequipped with a stop lamp,\u201d N. C. Gen. Stat. Ann. \u00a720\u2013129(g), requires only a single lamp\u2014which Heien\u2019s vehicle had\u2014and therefore the justification for the stop was objectively unreasonable. Reversing in turn, the State Supreme Court held that, even assuming no violation of the state law had occurred, Darisse\u2019s mistaken understanding of the law was reasonable,
\nand thus the stop was valid.<\/p>\n

Held: Because Darisse\u2019s mistake of law was reasonable, there was reasonable suspicion justifying the stop under the Fourth Amendment. Pp. 4\u201313.<\/p>\n

(a) The Fourth Amendment requires government officials to act reasonably, not perfectly, and gives those officials \u201cfair leeway for enforcing the law,\u201d Brinegar v. United States, 338 U. S. 160, 176. Searches and seizures based on mistakes of fact may be reasonable. See, e.g., Illinois v. Rodriguez, 497 U. S. 177, 183\u2013186. The limiting factor is that \u201cthe mistakes must be those of reasonable men.\u201d
\nBrinegar, supra, at 176. Mistakes of law are no less compatible with the concept of reasonable suspicion, which arises from an understanding of both the facts and the relevant law. Whether an officer is reasonably mistaken about the one or the other, the result is the same: the facts are outside the scope of the law. And neither the Fourth Amendment\u2019s text nor this Court\u2019s precedents offer any reason why that result should not be acceptable when reached by a reasonable mistake of law.<\/p>\n

More than two centuries ago, this Court held that reasonable mistakes of law, like those of fact, could justify a certificate of probable cause. United States v. Riddle, 5 Cranch 311, 313. That holding was reiterated in numerous 19th-century decisions. Although Riddle was not a Fourth Amendment case, it explained the concept of probable cause, which this Court has said carried the same \u201cfixed and well known meaning\u201d in the Fourth Amendment, Brinegar, supra, at 175, and n. 14, and no subsequent decision of this Court has undermined that understanding. The contrary conclusion would be hard to reconcile with the more recent precedent of Michigan v. DeFillippo, 443 U. S. 31, where the Court, addressing the validity of an arrest made under a criminal law later declared unconstitutional, held that the officers\u2019 reasonable assumption that the law was valid gave them
\n\u201cabundant probable cause\u201d to make the arrest, id., at 37. Heien attempts to recast DeFillippo as a case solely about the exclusionary rule, not the Fourth Amendment itself, but DeFillippo\u2019s express holding is that the arrest was constitutionally valid because the officers had probable cause. See id., at 40. Heien misplaces his reliance on cases such as Davis v. United States, 564 U. S. ___, where any consideration of reasonableness was limited to the separate matter of remedy, not whether there was a Fourth Amendment violation in the first place.<\/p>\n

Heien contends that the rationale that permits reasonable errors of fact does not extend to reasonable errors of law, arguing that officers in the field deserve a margin of error when making factual assessments on the fly. An officer may, however, also be suddenly confronted with a situation requiring application of an unclear statute. This Court\u2019s holding does not discourage officers from learning the law. Because the Fourth Amendment tolerates only objectively reasonable mistakes, cf. Whren v. United States, 517 U. S. 806, 813, an officer can gain no advantage through poor study. Finally, while the maxim \u201cIgnorance of the law is no excuse\u201d correctly implies that the State cannot impose punishment based on a mistake of law, it does not mean a reasonable mistake of law cannot justify an investigatory stop. Pp. 4\u201312.<\/p>\n

(b) There is little difficulty in concluding that Officer Darisse\u2019s error of law was reasonable. The North Carolina vehicle code that requires \u201ca stop lamp\u201d also provides that the lamp \u201cmay be incorpo rated into a unit with one or more other rear lamps,\u201d N. C. Gen. Stat. Ann. \u00a720\u2013129(g), and that \u201call originally equipped rear lamps\u201d must be \u201cin good working order,\u201d \u00a720\u2013129(d). Although the State Court of Appeals held that \u201crear lamps\u201d do not include brake lights, the word \u201cother,\u201d coupled with the lack of state-court precedent interpreting the provision, made it objectively reasonable to think that a faulty brake light constituted a violation. Pp. 12\u201313.<\/p>\n
